Sub Unit Locations

The MCPA is located at positions 3 and 4 in the cabinet. A WRH-V is equipped for one band in the cabinet and,

if required, an additional band in a high cover. PCBA positions are illustrated in Figure 1-6 and a block diagram

is located in Appendix A.

Fiber Optic Distribution Networks

Fiber optic networks are setup identically to data networks. WRH-Vs are connected in a star configuration as

illustrated in Figure 1-7. In this example, a Base Station Master Unit (BMU) is fed by a BTS via an RF cable. An

Optical Converter Module (OCM) could also be used depending on the system configuration. The BMU or OCM

contain three FONs and provide continuity to the FONs in the four WRHs. By using WDMs and Optical Splitters

(OSPs) in the WRHs, the distribution net can be built up with a combination of star and daisy-chain connections

using double or single fiber.
